First off, of the first four links, how many are on the current patch? Oh? zero of them, most of them are from the begining of this year, around 4.01/03. (Back when a tank meta did exist)
I just wanna clarify something real quick - I'm defending the proposition that season 4 has been a season of tanks. Season 4 has been ongoing for just shy of a year, and information from the beginning of that time period is just as relevant as information from the past week when we're evaluating the season as a whole.
By my approximation, there have been three vague epochs of top lane this season - at the beginning of the season, there was the 'tank meta,' where Renekton, Shyvana, Mundo and later Trundle were played almost every game. Near the end of the spring split of LCS, it transitioned into a more carry focused top lane where Jax and Kayle dominated, and other carry oriented picks like Ryze and Irelia did quite well. Around 4.10 or 4.11, both Kayle and Jax were nerfed, and a new breed of tanks focused on percentile damage reduction arose to deal with the newly buffed ADCs - Maokai and Gragas at first, then later Maokai and Alistar.
Overall, altho the exact tanks being played have differed, the strongest top laners have been tanks for the majority of season four. Thus, I feel that 'A season of tanks' is an accurate description.
Siting that [5][6][7] are tanks is bullshit, because if you look carefully you'll see "PRIMARY: Fighter"; it's like saying Gnar is an adc because his secondary role is "Marksman" it's a weak argument that doesn't make sense, because gnar can't perform and do the job a marksman does, just like shyv, renek and mundo don't have the peel to do a tanks job.
Marksman=/ADC. Someone who wants to play the role of ADC will likely chose a champion from the Marksman class, but someone playing a Marksman is not necessarily playing ADC.
Semantics aside, secondary roles are still roles - there's a reason that Shyvana is listed as a secondary tank rather than a secondary assassin (or even an exclusive fighter). She builds for and plays a tanky, initiation focused style.
Use currently relevant information; we're in an ADC dominated meta, not a tank one. (How many bans were devoted to tanks OTHER than alistar in worlds?)
However many were spent on Maokai, plus a bit of change. Don't have the stats in front of me atm, but I imagine there were several dozen.
